Review on 🚀 JDMSPEED Turbo Valve Cover Replacement 11127565284 for BMW 135I 335I 535I Z4 X6 Engine by Dick Grayson

Genuine cover is perfect for N54 2009 335i engine but the bolts provided are very soft and cross too easily. Edit: Removed one of the screws and the threads are terrible. See image. A thread error by the manufacturer caused serious problems. I've done valve covers before with no problems, I literally hand tighten each bolt with my fingers and then tighten them up to 7 ft lbs. following the BMW and BMW tightening pattern and 4 bolt heads came loose leaving me in the garage. GoodBolts Bad's coating just feels too soft and the quality feels poor, resulting in slight cross-threading. Process the first screw that was pulled out with a thread error. The gasket seems fine, didn't have a chance to start the car to see if it was leaking before the bolts broke.
